SAFE 'IY-PIN.

Specification of Letters Patent.

Patented March 24, 1908.

, Application filed September 4, 1906. Serial No. 333,249.

To all whom it may concern:

Be it known that I, ASA W. STRAIGHT, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Safety-Pins, of which the following'is a specification.

This invention relates to safety pins, and relates particularly to safety pins of the general type shown and described in U. S. Let ters Patent No. 7 841,968, issued to me March 14, 1905.

Primary objects of the invention are to provide a pin tong for safety pins of this type attached to the base or plate in such manner that it may be swung or turned laterally so that substantially the entire length of the tong will project beyond said base or plate in which position said base or plate will interfere the least possible with the insertion of said pin tong; to provide a pin of this type in which the tong is adapted to be secured to the base or plate by means of a suitable catch engaging the tong'adjacent to its point; to provide for replacing the tong in case it becomes bent or broken; and generally to provide a pin of this type, which will be of novel construction and will embody the features of ease of operation, efficiency, simplicity, strength and durability. To effect these various objects, a pin of my invention comprises the various features and details of construction hereinafter described and claimed.

In the accompanying drawings, in which my invention is fully illustratedFigur.e 1 is a perspective view of a safety pin embodying my invention, showing the pin tong turned laterally in dotted lines. Fig. 2 is a side view thereof, partly in section. Fig. 3 is a partial side View, on an enlarged scale and partly in section, illustrating a modified form of bearing for the pin tong.

Referring now to the drawings, 1 designates the base plate or shield of my improved pin and 2 the tong thereof mounted in a suitable pivot bearing formed in said base or shield 1, so as to turn laterally relatively thereto, said tong comprising a section 3 adjacent to its point of attachment to said base plate or shield 1, which extends substantially at right angles to said base plate or shield and a point section 4 which is forwardly inclined. Preferably, also, said tong 2 comprises an. intermediate section 5 which extends substantially parallel. with said base plate or shield 1.

Formed on the base plate or shield 1 is a catch 6 adapted to engage the pin tong 2 for the purpose of securing it in position. As shown, said catch 6 is formed integral with said base or shield 1 and is bent downwardly at an angle relatively thereto so as to extend about at right angles to the inclined section 4 of said pin tong. It is obvious, however,

that the shape and position of said catch admits of wide variation.

As shown in Figs. 1 and 2, the pin tong 2 is secured in a suitable pivot bearing formed directly in the base or shield 1, said pin tong being secured in its bearing by means of a head 7 thereon confined between the base portion proper 1 and an end section 8 thereof which is bent over upon said base portion proper. This construction will ordinarily be employed only in cheaper pins such as are designed to be thrown away when the pin tong becomes bent or broken.

In more expensive pins, as when applied to jewelry, in which the pin tong 2, if broken, would probably be replaced, it is desirable to provide a construction whereby the pin tong maybe removed and a new one substituted without in any manner affecting thebase plate or shield 1. This end may be eifected by the construction shown in Fig. 4, in which the head 7 of the pin tong 2 is confined or clamped between the base portion proper 1 of the pin and the inner end of a bushing 9 threaded to a suitable opening formed in the turned over end or section 8 of said base plate or shield. IVith this construction, it is obvious that the pin tong may be removed and a new tong substituted by merely unscrewing the bushing 9, replacing the broken tong with a new one and again securing said bushing 9 into its opening in the in.

In Figs. 4 and 5 of the drawing, I have shown still another modification of the pivot bearing for said pin tong 2, in which said pin tong is secured in its bearing in said bushin independently of the engagement of said bushing with the opening in said base plate or shield 1. In this modification the pin tong is secured in its bearing in the bushing 9 by means of a flange or projection 10 on the inner end of said bushing which is bent or turned inwardly over the end of the head 7 of the pin tong. This form of bearing, being entirely self-c0ntained, can be finished at the factory ready for insertion into the base plates and is thus of particular advantage shield l proper, instead of in a turned over end or section thereof. Obviously, also, if for any reason desired, the bearing for the pin tong bearing shown in Fig. 3 may likewise be formed directly in the base plate or shield 1, instead of in the turned over end. 8 thereof, as shown, and, if for any reason desired, the bearing shown in Figs. 4 and 5 may be formed in a turned over end 8 of the base plate or shield 1, instead of directly in said, base plate or shield proper.

I claim 1. A pin comprising a suitable base plate a portion of which adjacent to one end is turned back upon said plate and is provided with a pivot bearing for a pin tong, a pin tong mounted in said bearing and means for securing said pin tong in its bearing, said means comprising a head on said pin tong secured between said base plate and the turned over portion thereof. 7

2. A pin comprising a suitable base plate an end of which is turned back upon itself and is provided with a pivot bearing for a pin tong, a pin tong mounted in said bearing and means for securing said pin tong in its bearing, said means comprising a head on said pin tong secured between said base plate and the turned over end thereof.

3. Apin comprising a suitable base plate a portion of which adjacent to one end is turned back upon said plate and is provided with a hole or opening which extends through the same, a bushing removably secured in said hole provided with a pivot bearing for a pin tong, a pin tong mounted in said bearing and means to secure said pin tong in its bearing comprising a head on the end thereof of less diameter than the bearing bushing, said head being secured between the inner end of said bushing and said base plate.

In testimony, that I claim the foregoing as my invention, I affix my signature in presence of two subscribing witnesses, this 30th day of August, A. D. 1906.
